摘　　要：用同一只称重传感器使用不同的承压头将获得不同的测量精度.分析了单球面压头和不倒翁压头的传力情况,还对误差进行了分析.通过实验论证了受力点变化及压头不同均对传感器非线性、灵敏系数有明显影响.Different measuring accuracy is obtained by using the same transducer with different load cell. The load transference on both single spherical load cell and tumbler type load cell as well as the errors have been analysed. The experiments proved that different loading point and different load cell affect the non-linearity and sensitivity obviously.
